Nvidia Corp., a leading developer of core-logic sets and graphics processors, said that the problem with Serial ATA controller on its latest high-end core-logic sets is solved, however, some users are still reporting problems with Serial ATA operation on systems running nForce chipsets from the company. Earlier users in several forums, particularly, in EVGA and Nvidia tech support forums, reported about "lock up" and "disk error" issues with Serial ATA hard disk drives and RAID capabilities of the Nvidia nForce 680i SLI core-logic. Some end users even could not install Windows XP operating system, whereas others could not use their systems flawlessly for long and some even reported data corruption. The majority of customers, however, reported no problems. Later on EVGA and Nvidia issued a BIOS version that should fix the problems and make the systems more stable.

"The problem that some users were experiencing related to signal timings on the motherboard. The new BIOS (P32) corrects this," said Drew Henry, Nvidia's chipset chief, in an interview with [H]ard|OCP web-site. Nvidia now blames its internal quality assurance process for not detecting the issues early and claims that in future there will be no such situations when end-users discover issues not seen by the core-logic developer. "We should have caught this in our internal QA process. Unfortunately, we didn't, and we have adjusted internal processes to make sure that this does not happen again," Mr. Henry said.
